            This function is used to send data on the stream socket. The function
            call will block until one or more bytes of the data has been sent successfully,
            or an until error occurs.

<p>
            The send operation may not transmit all of the data to the peer. Consider
            using the <a class="link" href="../../write.html" title="write"><code class="computeroutput">write</code></a>
            function if you need to ensure that all data is written before the blocking
            operation completes.

            To send a single data buffer use the <a class="link" href="../../buffer.html" title="buffer"><code class="computeroutput">buffer</code></a>
            function as follows:
          </p>
<pre class="programlisting">socket.send(asio::buffer(data, size));
</pre>
<p>
            See the <a class="link" href="../../buffer.html" title="buffer"><code class="computeroutput">buffer</code></a>
            documentation for information on sending multiple buffers in one go,
            and how to use it with arrays, boost::array or std::vector.
